Fremont Setbacks & Height Limits — Residential Zones

Last updated: Verified:

Fact-checked against the City of Fremont Single Family Residential Zoning Standards handout updated June 4, 2026, and current California ADU law on September 21, 2026.

Fremont's single-family dimensional standards depend on the exact R-1 district and, in several neighborhoods, on a named subdistrict, Planned District (PD), or Planned Unit Development (PUD). The City's 2026 handout expressly warns that PD/PUD standards can modify the base zoning.

Current Base R-1 Standards

For several common base districts, the City's June 2026 handout lists:

Standard R-1-6 R-1-8 R-1-10
Front yard 20 ft 25 ft 25 ft
Rear yard — first story 25 ft 25 ft 30 ft
Rear yard — second story 25 ft 30 ft 35 ft
Interior side — first story, minimum 5 ft 7 ft 8 ft
Interior side — first story, total both sides 12 ft 16 ft 20 ft
Interior side — second story, minimum 6 ft 8 ft 10 ft
Interior side — second story, total both sides 15 ft 20 ft 20 ft
Street-side yard 10 ft 12.5 ft 12.5 ft
Maximum principal height — two story 30 ft 30 ft 30 ft

The previous page described some of these as approximate ranges and omitted the required aggregate side-yard dimensions. In Fremont those total-side requirements are part of the current table and should be checked along with the minimum on each side.

One-Story Height Is Also Regulated

The City's handout separately lists a 17-ft maximum principal-building height for a one-story structure in these base R-1 districts. A two-story building may reach the district's listed two-story maximum, normally 30 ft in the base R-1-6/R-1-8/R-1-10 districts.

Certain named subdistricts, such as Mission Palms or Mission Ranch, use modified height and roof-pitch standards.

Planned Districts and PUDs

The current Fremont handout states that some single-family homes lie within PDs or PUDs with their own modified zoning standards.

For those parcels:

  1. use the zoning shown in Fremont eGIS;
  2. retrieve the PD/PUD development standards associated with the parcel;
  3. use the base district only where the project-specific standards do not replace it.

Hillside and Special Conditions

R-1-20 and R-1-40 use substantially larger setbacks. Hillside areas and other overlays can add grading, height, and massing constraints beyond the base table.

Additions to existing houses also require review of nonconforming conditions, roof pitch, finished-floor elevation, and other standards in the City's handout.

California State ADU Law

Current State ADU Law is codified at Government Code §§66310–66342. Older references to §65852.2 are outdated.

Current state law generally does not allow a city to require more than a 4-ft side or rear setback for a new-construction ADU. ADU height depends on the statutory configuration and current local implementation.

See the Fremont ADU rules page for ADU-specific guidance.

How to Check a Property

  1. Confirm the zoning district in Fremont eGIS.
  2. Check whether the parcel has a named R-1 subdistrict, PD, or PUD.
  3. Use the current §18.90.040 standards for the exact district.
  4. Distinguish first-story from second-story rear and side setbacks.
  5. Check total side-yard width as well as the minimum on each side.
  6. Confirm unusual conditions with Fremont Planning before relying on a design dimension.

FAQ

What are the setback requirements in Fremont R-1 zones?
In Fremont's R-1-6 zone, the front setback is 20 ft, side setbacks are 5 ft for one-story and 6 ft for two-story, and the rear setback is 25 ft. R-1-8 and R-1-10 zones have larger setbacks — 25 ft front, 7–10 ft sides, and 25–35 ft rear. Always confirm your lot's specific district on the Fremont zoning map.
What is the maximum building height in Fremont residential zones?
Maximum building height in Fremont's R-1 single-family districts is 30 ft, measured from average grade. Multi-family R-3 districts allow up to 36 ft, and the C-N neighborhood commercial district allows up to 35 ft. Hillside overlay areas and design review zones may impose additional limits.
How is lot coverage calculated in Fremont?
Lot coverage in Fremont's R-1 single-family zones is capped at 40 percent of the lot area. R-3 multi-family districts allow up to 50 percent. Coverage is based on the ground footprint of buildings — see Fremont Municipal Code Title 18 for the specific definition and exclusions.
Do California ADU laws override Fremont's setbacks and height limits?
Yes. Under California state ADU law (AB 68, SB 13, AB 881, AB 2221), Fremont must allow detached ADUs with 4 ft side and rear setbacks and up to 16 ft in height on single-family lots (25 ft for attached ADUs). These state minimums override stricter local zoning for qualifying ADU projects.
